IMPROVEMENT IN MACHINES FOR TURNING WOODEN HEELS.

Specification forming part of Letters Patent No. 208,989, dated'Oetober15, 1878; application filed September 28, 1878.

To all whom it may concern:

Be it known that we, LOUIS PRENOT and GEORGE MARGHAL, of the city,county and State of New York, have invented a new and useful Improvementin Machines. for Forming \Vooden Heels for Boots and Shoes, of which-the following is a specification:

Figure 1 is a top view of our improved machine. Fig. 2 is a verticalsection of the same, taken through the line a: a, Fig. 1. Fig. 3 is adetail top view of the gage and blank holder.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to furnish an improved machine forforming wooden heels for boots and shoes, which shall be so constructedas to form the heels rapidly and accurately, and shall be simple inconstruction and convenient in use.

The invention consists in the combination of the two rollers, theintermediate shaft provided with the pulley, and the cutters, and theholder provided with the two gages or patterns, and the clamp forholding the blank, with each other and with the frame and the slottedguide-standards, as hereinafter fully described.

A represents a rectangular frame, which is supported upon legs B, ofsuch a length that the operating parts of the machine may be at aconvenient height. To the end parts of the side bars of the frame A areattached bearin gs, in which revolve the journals of the two rollers C.The rollers O are made of such a size as to fit into the concavity ofthe heel to be formed. To the side bars of the frame A, midway betweenthe bearings of the rollers O, are attached bearings, in which revolvethe journals of the shaft D. The bearings of the shaft D are providedwith set-screws, so that the said shaft may be adjusted higher or lower,as may be required. To the shaft D, near one end, is attached, or uponit is formed, a pulley, E, to receive the belt by which the said shaftis driven. shaft D are formed, or to it are attached, cutters F. G isthe holder, upon the ends of which are formed, or to them are attached,cylindrical handles. To the holder G are at- Upon the other part of the't-ached, in such positions as to rest upon the I is held in place byclamps, one part, J, of

which is stationary and is rigidly attached to the holder G. The otherpart, K, is movable, passes through a slot in the holder G, and isadjusted and held in place by a pin, L, passed through it above the saidholder, and by a screw, M, swiveled to it, and which passes through asupport, N, attached to the said holder G. The cylindrical end parts ofthe holder G are placed in guide-slots in standards 0, attached to theend bars of frame A.

With this construction, when the blank I has been secured to the holderG, the said holder is placed in the guide-slots of the standards O, withone of the gages H resting upon one of the rollers C, and the said blankI restin g upon the cutters F. The blank I is then pressed down upon thecutters 1? until the other gage H comes in contact with and restssquarely upon the other roller 0, the holder G being turned until allparts of both gages H rest squarely upon both rollers 0, when the blankI will be found to have the exact shape of the two gages. The finishedheel is then removed and another blank is secured to the holder G.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination of the two rollers O, theintermediate shaft D, provided with the pulley E and the cutters F, andthe holder G, provided with the two gages or patterns H, and the clamp JK L M, for holding the blank, with each other and with the frame A B andthe slotted LOUIS PRENOT. GEORGE MAROHAL.
